A Report of SRD-based UWB Pulse Generation and Implementation

超宽带无线通信技术是一种利用纳秒及亚纳秒量级的极窄脉冲作为传输载体的无线技术。文中利用SRD(阶跃恢复二极管)与微波传输线,通过错位对消的方法设计与制作了UW B脉冲发生器。对电路的仿真结果和测量结果进行了比较分析,成功地产生了纳秒级宽度的UW B极窄脉冲信号,对今后利用阶跃恢复二极管和微带线产生窄脉冲有较好的参考价值。

Ultra Wideband（UWB） radio technology is a technological advancement through using narrow nanosecond or subnanosecond pulse as transmission carrier. This paper is a report of the designing and making of a UWB pulse generator using SRD（step recovery diode） and microwave transmission line and by means of intervention and elimination. The data from the simulation and those from the test of the circuit are presented and analyzed, which shows successful generation of nanosecond UWB narrow pulse signal. This assumes valuable implications for the use of step recovery and microwave transmission line in generating UWB pulse in future work of UWB radio technology development.
